-+ **develop**  the actively worked on next release of the app, what we branch off of while working on new features and what we merge into upon feature completion
-+ **feature/** or feature/\<username\>/ any branch under this directory is an actively developed feature, feature branches culminate in a PR, are merged and deleted.
- Typically a feature branch is off of develop and into develop but in rare scenarios if there is an issue in production a branch may be made off master to fix this issue, this type of feature branch must be merged to develop and master before being deleted.
